BAHA: Bone-Anchored Hearing Aid.
Bone-Anchored Hearing Aid (BAHA) has proven performance and advantages for patients with aural atresia or chronic ear drainage who cannot wear air-conduction hearing aids. The BAHA has both cosmetic and acoustic advantages over most conventional hearing aids and hence is becoming increasingly popular. Moreover, BAHA improves the quality of life and has also significantly reduces ear discharge. ...
متن کاملBone Anchored Hearing Aids (BAHA)
Bone Anchored Hearing Aids (BAHA). The bone anchored hearing aid or BAHA is a small vibrator that can be reversibly plugged onto a titanium screw that is implanted behind the ear. It transduces sound into vibration of the screw and stimulates the cochleae by means of the bone conduction pathway. The main indications are conductive hearing loss or mixed hearing loss with a moderate perceptive co...
متن کاملImproving the Accuracy of Baha® Fittings through Measures of Direct Bone Conduction
OBJECTIVES Variability in Baha® sound processor fittings may arise from the nature of the implant-to-bone transmission as well as transcranial attenuation for patients with single-sided sensorineural deafness (SSD). One method of improving the predictability of Baha fittings is to measure the individual patient's actual bone conduction thresholds, thereby removing the influences of skin thickne...
متن کاملThe bone-anchored hearing aid compared with conventional hearing aids. Audiologic results and the patients' opinions.
The bone-anchored hearing aid (BAHA) was evaluated in 65 patients by comparing speech recognition and questionnaire results with those obtained with the patients' own previous hearing aids. In the majority of patients who previously used a conventional bone conductor, significantly improved speech recognition scores were found with the BAHA. The majority preferred the BAHA to their previous bon...
متن کاملTransient Analysis of the Single-Conductor Overhead Lines Connected to Grid-Grounded Arrester under Direct Lightning by Means of GA
In this paper, genetic algorithm-based approach for transient analysis of single transmission line connected to arrester is proposed. In this approach, the lightning channel striking the overhead line is first represented by a current source and this source is truncated by a finite set of frequency harmonies in time domain. Norton equivalent circuit viewed across arrester is then computed by me...
